I found the answer to my own question.
Excerpt of my message (sent 11 March 2003):
> Since I upgraded to RH 8.0, perldoc is acting weird. You see, e.g.,

The reason is that 'less' has changed slightly in 8.0 (wrt. 7.1).
>From the 'man less' page:
-r or --raw-control-chars
Causes "raw" control characters to be displayed. The default is
to display control characters using the caret notation; for
example, a control-A (octal 001) is displayed as "^A".
[...]
-R or --RAW-CONTROL-CHARS
Like -r, but tries to keep track of the screen appearance where
possible.
And I had my environment variable PAGER set to 'less'. Changing it to
'less -R' (--RAW-CONTROL-CHARS) fixes perldoc.
